Colombia striker Jackson Martinez, former Chelsea midfielder Ramires, Cameroon captain Stephane Mbia and ex-Serie A duo Gervinho and Fredy Guarin are among the other big Chinese signings in 2016.

The transfer window closes in China on 26 February.

Martins burst into the international limelight at Italian side Inter Milan before switching to Newcastle in August 2006. He scored 35 goals in his three seasons with the Magpies, later joining Birmingham City on loan in 2011.
